To allwho'mit may concewt:

Be it known that I, Hnmnlo'n EcKER'rz, residing at Essen-Rellingkhausen, Germany, a citizen of the German epublic, have invented a certain new and useful Im rovement in- Apparatus for Loading Iotor Vehicles, for which I have filed applications in Germany, filed February 6, 1920, Patent No. 356,877 France, filed March 29, 1921; Italy, filed March 22, 1921; Great Britain, filed March 17 1921, of which the following is a specification.

This invention relates to motor vehicles, which serve for the conveyance of loose material or the like (e. g. sand, coal, dust, etc).

The invention consists in an arrangement of a conveyor screw in such a way that the material can be pressed by the screw into the-closed body of the vehicle.

The invention will be described with reference to the accompanying drawings which show two embodiments of the subject-matter of the invention by way of example.

In these drawings- Figure 1 shows a side elevation, partially in section, of the first embodiment of the ap aratus together with the vehicle,

igure 2 is the top plan view ofFigure 1,

Figure 3 is a section on the line 33 ofFigure 1,

Figure 'shows on a larger scale a detail in longitudinal section,

Figure 5 is a section on F i re 4. j

igure' 6 is a side elevation of the second embodiment of the apparatus together with the line-H or the vehicle.

Figure 7 is the top plan view corresponding to Figure 6 and igure 8 is the right hand end view of Figure 6.

The arrangement shown in Figures 1 to 5 will be described first.

The vehicle has a-body A (see Figure 1) which is closed at the top by a cover particularly in the loadin process and has dis charging doors a at t e sides. The vehicle is loaded by a'conveyor screw which con- -sists of two parts B, B (see Figure 1). The shaft B of the conveyor screw ortion B lies in the vertical longitudinal p ane of the vehicle. At the same time the shaft B is inclined rearwards and downwards. The

Fi 'tu said shaft 13 is driven by the motor of the vehicle through the medium of a horizontal shaft B and a countershaft B The screw portion B, which terminates immediately behind the body of the vehicle, works in a tubular piece G which is inserted in the rear wall a? of the body of the vehicle and in the interior of the latter passes over into a trough C (see Figure 1). The screw portion B works in a trough D, which can be rocked about a horizontal axis. For this purpose a bolt E, on which the trough D is mounted by means of eyes al is carried in eyes a and 0 (see Figures 2. and 3) which are mounted on the rear Wall a of the body ofthe vehicle and on the tubular piece 0. The shaft 13 of the portion B of the screw is adapted to rotate at its outer end in a. bearing F mounted on the trough '1). The other end of the shaft B can be coupled to the shaft B by means of a claw clutch. This clutch has a sleeve G (see res 4. and 5) which is movable longiinally in the shaft B against the action of a 'sprin g (see Figure. 4), but is connected tot e shaft so as to be incapable of rotating separately by a feather and move. On this sleeve there is. mounted a -c aw g (see particularly Figure 5) I against which a claw b which is mounted on a journal I) of the shaft B is adapted to bear.

The trou h D with the portion 13 of the screw, is a apted to be drawn up ofi the ground by means of a windlass,,the rope H of which see Fi res 1 and 2) is assed over a fixed roller 1 to the drum the Windlass. On the trough D is mounted a roller J (see Figure 1) for the purpose of supporting the trough upon the ground. The trough is also provided with an' eye (1 shaped like the linker a chain (see Figure 1) which serves to secure the trough in the operative position by means of a hook] c -mounted on the tubular piece C.

When the trough'l) is in the operative position in which the roller J rests upon .the ground, the portion B of the screw forms an extension of the part B of the screw.

The claw b" is situated in the path offthe claw g or the claw b has pushed the sleeve G, if ithas got behind the claw y when 9 In the latter case the clutch b 9 will be thrown into engagement after a slight rotation of the shaft B In the operative ition of the trough D its outer end lies immediately above the ground.

When it is desired-to transfer material such as coal or sand lying on the ground to the body of the vehicle the latter is run backwards up to the material, the screw B B started and supplied with the material by a shovel or by running the vehicle farther back or movin it sideways.

The pitch the screw decreases towards the interior of the body of the vehicle, so that during the working ofthe screw a pres sure efiect is produced by'which the material is pressed into the body of the vehicle closed by its cover and also distributed therein.

, When the vehicle is traveling the trough D is turned up together with the portion B of the screw. v

In the arrangement illustrated in Figures 6 to 8 a conveyor screw M consisting of one Not piece is provided, the tubular casing which terminates behind the body of thevehicle at some height above the ground. The casing N is closed .at the rear bya bottoin 11. in which the shaft M of the screw is carried in a bearing. At the top on 'the other hand the casing N has an opening,-

into which a hopper or'chute P opens. To

this hopper is fixed a hook p for buckets R for the material particularly dust) -t0 be conveyed by the ve icle. Two pron s S (see Figure 6) are also provided on the cover of the body of the vehicle for the purpose of detaching substances such as rags, etc., 00 curring in the dust and which have become wrapped round the shaft'M.

The dust is brought to the vehicle in the buckets R which are then attached to the hook 1 and tipped into the hopper P, so that t e dust can be conveyed into the body of the vehicle by the screw M which is driven by the motor of the vehicle. When the body of the vehicle is full its cover becomes raised by the pressure of the dust forced into the body by the screw. The

drivin mechanism of the screw is then sto laims.

1. A vehicle having in combination a closed receptacle and a screw conveyer for loading the vehicle, said conveyer entering the receptacle near the bottom thereof and being provided with a stationary casing at its point ofentrance, whereby the forcin action of the conveyer on the load combined with the restraining action of the walls of the container efi'ects a complete filling of the container.

tion being in afixed position and connected by a hinge at the top of its lower extremity. to the exterior portion, means whereby the latter, through the uncoupling of the screw members of the respective ,portions, may at will be swung upward and inward or again brought into w rking aligllm for holding the said portions and their component parts in this position.

cut and means I 4. A construction as described in claim 8 in which the screw member consists of two' joined portions, thepitch of the said screw member as a whole decreasing towards its inner end as and for the'purpose hereinbefore described.
